Title: Curing catalyst
Inventor: KOERNER GOETZ DR
IPC: C08K5/00
Filed: 1982-04-22
Abstract: The curing of organo-modified polysiloxane resins obtained by partial reaction of alkoxypolysiloxanes with organic polyols is accelerated by a catalyst prepared by reacting from 1 to 2 mol of a polycarboxylic anhydride with 1 mol of a compound of the formula <IMAGE>  in which R<1> and R<2> are identical or different and are <IMAGE> groups, and R<3> is an alkylene, cycloalkylene or phenylene group, subsequently reacting this intermediate with from 0.4 to 6 mol of Ti(OR<4>)4 (R<4> is an alkylene group having 1 to 6 carbon atoms) with removal of the alcohol R<4>OH, it being possible to terminate the reaction after at least 25% of the theoretical amount of R<4>OH has been liberated. The catalyst according to the invention is stable to hydrolysis. If it is used for the curing of thermocurable polyester-polysiloxane resins, coatings are obtained which have high hydrolysis resistance and weathering resistance.

Title: Hydraulically acting shock absorber and vibration damper
Inventor: BRAND ERICH
IPC: F16F9/48
Filed: 1982-05-12
Abstract: The invention relates to a hydraulically acting damper, especially a shock absorber having a cylinder in which a piston that is connected to a piston rod projecting out of the cylinder can be displaced and in which the piston interacts with a circulating flow opening. The internal space of the cylinder is separated into two chambers, one of which is filled with a compressible medium and the other with an incompressible medium. The circulating flow opening is formed by a recess which is arranged on the piston edge and is open to the piston edge and a wedge or the piston engaging into the recess as a function of the piston position, and a groove which runs axially in the cylinder inner wall, the cross-section of the channel or of the wedge varying in the axial direction and the circulating flow opening being of minimum size at least in one position of the piston, and the incompressible damping medium being a homogeneous paste consisting of at least finely divided solid and a temperature-stable polyglycol ether, polyglycol ester and/or saturated carboxylic acid ester or silicon oil.
Patent DE-3219690-A1 (DE)
Title: Continuous plant for treating workpieces
Inventor: BRAEUTIGAM JUERGEN ING GRAD
IPC: B65G15/36
Filed: 1982-05-26
Abstract: In a continuous plant for treating metallic workpieces, which also includes a temporary low pressure effect, the open workpiece holders, which receive the workpieces, are covered by a co-running sealing band made of rubber or plastics. In order to avoid an impermissible local bulging of the sealing band into the workpiece holders, which are under low pressure, due to the effect of external atmospheric pressure, the sealing band according to the invention is stiffened with cord elements embedded in both the longitudinal and the lateral direction in a novel layer structure having lateral inserts provided in pairs in each case on both sides of the longitudinal inserts at a distance from these. Whilst maintaining the necessary flexibility for unrestricted circulation, the sealing band thereby obtains sufficient stiffness for perfect covering of even large-area workpiece holders.

Title: Monitoring device for the energy supply to a plant actuated by pressure medium
Inventor: BURGDORF JOCHEN
IPC: B60T17/22
Filed: 1982-07-21
Abstract: An interruption in the energy supply of a plant actuated by pressure medium is to be recognised with the arrangement according to the invention, before a critical or dangerous state is reached. For this purpose, the operating states of the device for replenishing the pressure reservoir of the energy supply are determined, and at least one time threshold (e.g. t3) is given in advance at which the replenishing device must have reached a given operating state after being switched on, when the energy supply is functioning normally. If the said operating state is not reached on reaching this time threshold, an alarm signal is generated. In particular, an alarm signal is generated when the replenishing device remains switched on for longer than is required, with a normally functioning energy supply, in order to replenish the pressure reservoir from the pressure value for switching on to the pressure value. <IMAGE>

Title: Concentration of pollutants in the laboratory for concentrated and distributed dispersion
Inventor: HILBERS HEINRICH ING GRAD
IPC: B08B15/02
Filed: 1982-08-30
Abstract: Pollutants in the chemical laboratory disperse on laboratory benches and in fume extraction cupboards. The contingent proportion of external air for ventilating the laboratory room is reduced if, according to this invention, the air-spiral column effects, for example, a concentrated dispersion of pollutant in an annular manner around the source and leads it to the extraction opening. This is also achieved if, apart from the air-spiral column and in particular in the case of a distributed dispersion of pollutant, boundary screens provided at the edge of the surface concentrate the pollutant gases and divert them to the spiral column. In this manner these gases too are led to the exhaust opening. <IMAGE>

Filed: 1983-03-09
Abstract: In a process for producing seed magma, slightly supersaturated intake syrup which is only a fraction of the total batch to be produced is seeded with slurry while being continuously stirred. This magma is then subjected to a first crystallisation by cooling. Further saturated intake syrup is then added in the same volume or a multiple of the starting volume while continuously stirring. This magma is subjected to a second crystallisation by cooling. Said magma is then subjected to a crystallisation by evaporation while continuously stirring, with fresh concentrated syrup being added simultaneously until the desired crystal content of 35 to 45% and final volume have been reached.
Patent DE-3311650-A1 (DE)
Title: Method of producing high-purity silane and high-purity hyperpure polycrystalline and monocrystalline silicon for solar cells and semiconductors
Inventor: BRENEMAN WILLIAM CALVIN
IPC: C01B33/029
Filed: 1983-03-30
Abstract: Silicon tetrachloride, hydrogen and metallurgical silicon are reacted at about 400 to 600 DEG C at a pressure of more than 6.9 bar, and particularly between 20.7 and 41.4 bar, with the formation of di- and tri-chlorosiloanes. The latter are disproportionated in the presence of an anion exchanger with the formation of high-purity silane. Byproducts and unreacted material are recycled, while practically only silicon and hydrogen are consumed. Silane is further purified by means of activated carbon or by cryodistillation, and finally decomposed in a fluidised bed or in a free space to form high-purity polycrystalline silicon and hydrogen as byproduct, which is recycled. The method is simplified with respect to process products to be removed and permits an improvement in the overall reaction of metallurgical silicon to form silane and high-purity silicon which can be used for solar cells and semiconductors.

Title: Method for mixing dispersed solids according to the gravity principle
Inventor: BRACHEL HELMUT VON DR
IPC: B01F5/10
Filed: 1984-02-08
Abstract: In this method for mixing dispersed solids according to the gravity principle, use is made of emptying a container which is filled with the mixture of solids and which is subdivided into chambers by vertically extending, radial or coaxial separating walls, which are continuous or are provided with suitable perforations. In order to ensure a fully satisfactory mixing effect, especially for adhesive and cohesive materials, while the installed surface is distinctly reduced at the same time, one chamber in the container subdivided into two chambers of equal volume at the start of the mixing process is filled entirely, and another chamber is filled only to about half its volume, an approximately equal volume flow is then removed from both chambers simultaneously by gravity, and the volume flows combined after leaving the chambers are again filled back into the container at the top by means of a conveyor, in such a way that the chamber which, at the start of the mixing process, had been filled entirely remains filled virtually entirely, and the chamber which originally had been half full remains approximately half full.
